## anonymous one year ago Given the geometric sequence where a1 = 2 and the common ratio is 4, what is the domain for n? All real numbers All integers where n ≥ 0 All integers where n ≥ 1 All integers where n ≥ 2

by definition, a sequence is a function from the set of natural number to a subset of real number: $\Large n \to {a_n},\quad \mathbb{N} \to \mathbb{R}$ in your case it is $\Large n \geqslant 1$
